Matt, thanks. One question is for the acpi patches you sent before, do you think they are still necessary as a fix for the bgrt problem and coexist with the "reserve useful boot services" proposal?
No, the previous ACPI patches I sent can be thrown in the bin if we go with the approach outlined in this email. This approach is superior because it allows useful features such as ESRT and the new memory attributes to be used for kexec boot - the ACPI patches prevented a crash by disabling BGRT.
